PROBLEM TO BE SOLVED: To provide a bus system in a split system having higher performance. SOLUTION: A response time table 14 stores a response time 23 to the read command of a target module 4. A response counter 15 measures an elapsed time 24 after the execution of the read command issued by a master module 2 is started. A difference calculating part 16 calculates a time difference 25 between the response time 23 and the elapsed time 24. A command selecting part 12 selects a command to be executed from among the received commands, and a command issuing part 13 issues the selected command to a bus 8. When another command is received during waiting for a response to the read command, the command selecting part 12 selects the command as a command to be executed as long as the execution of the command is completed in a time difference 25 or less.
